TEAC AP-701

The TEAC AP-701 is a new flagship stereo power amplifier that delivers all the elements needed to amplify signals at the highest levels, setting a new level of excellence. The AP-701 model is equipped with highly efficient Hypex NCore amplifier modules (class D), which have undergone special “tuning” in order to best meet the specified parameters. The power supply includes a powerful power toroidal transformer and a rectifier section based on ultra-fast Schottky diodes. Thanks to this equipment, it is possible to increase the efficiency of the amplifier, reduce heating, minimize distortion and ultimately obtain accurate, clear and dynamic sound.

In normal stereo mode, the device produces 170 W per channel at 8 ohms, and in bridged mono connection BTL (Bridge Tied Load) the output power reaches 260 W (8 ohms). Biamping mode (dual mono) is also available. As for the circuitry, a fully balanced topology is used here, and the amplification section provides reliable protection against overvoltage, overheating and current overloads. If there is no signal for a certain period of time, the terminal automatically goes into standby mode with minimal power consumption.

A distinctive feature of the TEAC AP-701 is its design in the spirit of audio equipment of the 70-80s with neat dial indicators of the output signal level, which received a “warm” yellow backlight with 4-step dimming. The amplifier housing is made of massive 3mm thick aluminum panels, but has a flexible structure that allows vibrations to be controlled. Gimbals are used at the panel junctions to control the vibrations of the entire unit to ensure an open and vibrant sound reproduction. The aluminum case is traditionally equipped with stylized branded rack ears and patented anti-vibration supports (3-position Pin-Point foot system). According to audiophile traditions, and also due to low heat generation, the model uses only passive cooling.

The rear panel of the TEAC AP-701 contains two balanced input XLR connectors, as well as a pair of standard unbalanced RCA input connectors. To connect speaker systems, large screw terminals with gold-plated contact surfaces are used. The amplifier is available in silver or black color scheme.
